Question

LINES AND ANGLE
Example 1: In Fig. 6.9, lines PQ and RS
intersect each other at point 0. If
Z POR: ZROQ = 5:7, find all the angles.
Solution : Z POR +Z ROQ = 180°
(Linear pair of angles)
But Z POR: Z ROQ = 5:7
(Given)
5
Therefore,
Z POR =
x 180° = 75°
12
7
Similarly,
Z ROQ
x 180° = 105°
12
Now,
Z POS = ZROQ = 105°
and
Z SOQ = ZPOR = 75°​
